代码生成器 code generator是LLVM中最复杂的一个部分,任务是将相对high-level,不依赖目标机器的LLVM IR转化为 low-level的,依赖目标的机器指令(Machine Instr)。在生成Machine Instr之前,LLVM IR的指令会经过“Selection DAG node”转化。 Selection DAG Node Selection DAG Node是由Selection DAG Builder在Selection DA...

The LLVM target-independent code generator is a framework that provides a suite of reusable components for translating the LLVM internal representation to the machine code for a specified target—either in assembly form (suitable for a static compiler) or in binary machine code format (usable for ...

Beyond being implemented as a language, LLVM IR is actually defined in three isomorphic forms: the textual format above, an in-memory data structure inspected and modified by optimizations themselves, and an efficient and dense on-disk binary "bitcode" format. The LLVM Project also provides tools...

- 先自己从源代码 (http://llvm.org/releases/) 编译llvm和clang,或者直接安装clang for Windows - 测试过使用cygwin (https://cygwin.com/install.html) 中安装的libc++,以及cygwin带的mingw编译,失败 - 测试过安装mingw (http://mingw.org/) 到默认位置,并安装gcc-g++,编译成功 - 测试OSL渲染,bitcode加载...
on-disk binary bitcode format(.bc) 可以用llvm-as将.ll转化为.bc,也可以用llvm-dis将.bc转化为.ll文件 IR作为中间层,一方面可以让Optimizzer在没有前后端干扰的情况下工作,一方面在设计的时候也需要考虑到前后端。 一般来说,大多数发生在IR上的优化都遵照以下格式: ...
This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM. Other components include: the libc++ C++ standard library, the LLD linker, and more. Getting the Source Code and Building LLVM The LLVM Getting Started ...
